I think you intended writing #30 as his pay rise instead of #30000. I solved the problem using #30 as his annual pay rise.
Answer:
The man's initial salary was #714
Step-by-step explanation:
Extracting the key information from the question:
*** A man got a pay raise for 10 years.
*** His current salary is #1,014
*** He gets a pay raise of #30 annually.
*** We are simply required to calculate his initial salary before he started receiving pay rise.
Now, To calculate his initial salary before he started receiving pay rise, let us denote that initial salary that we are currently unaware of by "a".
Since his salary as at today is #1,014 and he has also received this pay rise of #30 for 10 years, we can calculate his initial salary before he started receiving pay rise every year with the following equation:
a + 30(10) = 1014
That is -
Initial salary + [pay rise × number of years] = current salary.
a + 30(10) = 1,014
a + 300 = 1014
a = 1014 - 300
a = #714
Therefore the man's initial salary was #714
Answer:
Triangle(C)
Step-by-step explanation:
All the Exterior Angles of a polygon add up to 360°, so: each exterior angle must be 360°n (where n is the number of sides). So, 360n=120 ; n=360/120=3 It is a triangle.
Answer:
Portion of walking in degrees = 72°
Step-by-step explanation:
The question is incomplete as the diagram is not shown in the question. I have attached the full question below. Consult it to understand the solution better
First calculate the percentage of walking from a total of all activities.
Percentage of walking = 10/50 · 100%
Percentage of walking = 20%
It means the portion of the circle(pie chart) for walking should be equal to 20% of the whole circle.
We know that the whole circle is equals to 360°
Circle = 360°
We need to calculate 20% of 360°, which will represent the portion of walking in degrees.
Portion of walking in degrees = 20/100 · 360°
Portion of walking in degrees = 72°
